This image was the result of having a quick go at the Strobist 'Film Noir' assignment. I had also quickly made a DIY cereal box snoot for the job. The shot was taken with an SB800 at camera left on 1/128th power, camera settings were 1/200th second, f8, ISO 100. The ambient light was very low. I need to experiment a bit more with some different light modifiers.The black and white conversion was done in Photoshop with the Channel Mixer palette. All you need to do is tick the monochrome check box and then play with the red, blue and green sliders. The accepted wisdom seems to be that keeping the total of the values for these colours at 100 achieves best results.
